Solutions; Vegetative propagation is a kind of propagation mode in which vegetative organs (roots, leaves and stems) of plants produce new individuals, which is called vegetative propagation. For example, potato tubers, thistle roots, strawberry creeping branches and begonia leaves can all germinate, and these buds can form new individuals. People often use asexual propagation methods such as rooting, cutting, grafting, scion and rootstock to propagate flowers and fruit trees. The leaves of pepper grass can germinate.
